Answer 2

ANSWER :

The blood helps in the transportation of oxygen and carbon-dioxide in humans.

The R.B.Cs have a large surface area which helps them to absorb oxygen and carbon - dioxide on their surface ,

The R.B.Cs have haemoglobin in their surface.

This particularly forms oxy-haemoglobin with oxygen and carbamino-haemoglobin with carbon-dioxide .

This breaks up to give oxygen in the tissues and it transports carbon-dioxide from tissues to lungs.

This way they are transported throughout the body !
